[0003] For the reconstruction of the old blast furnace, because the blast furnace is surrounded by the furnace frame, the driving height of the lifting blast furnace top is limited (the distance between the lower part of the driving car and the top of the furnace frame is small), and the furnace belt cannot be lifted above the furnace frame by driving. After moving horizontally, put it in the hob
Therefore it is not possible to dress

Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0025] see figure 1 There is an opening at the lower side of the grate 1, and two parallel moving beams 2 extending horizontally into the grate 1 are arranged at the opening, and the distance between the two moving beams 2 is greater than the maximum diameter of the blast furnace. A track 3 is arranged on the push beam, and the push cart 4 is rolled on the track by the roller 5 at the bottom. The car is connected.
[0026] The furnace shell is composed of 16 furnace zones from bottom to top, which are sequentially composed of the first furnace zone, the second furnace zone,..., and the 16th furnace zone.
[0027] The method of combining the upside down and the upside down of the blast furnace shell is as follows.
[0028] see figure 2 , the first furnace belt 101 is transported into the furnace frame by a trolley, and then the first furnac...

The invention provides a method for inversely installing a blast furnace shell, which is particularly suitable for the transformation of a blast furnace with a furnace frame around. By using the method, the construction cost can be reduced, and the construction speed is quickened. According to the method for inversely installing the blast furnace shell, the furnace shell consists of a first furnace zone, a second furnace zone,..., and a n-th furnace zone from top to bottom in sequence. The method comprises the following steps of: forming an opening in one side of the lower part of the furnace frame, feeding the n-th furnace zone into the furnace frame from the opening, lifting the n-th furnace zone through a traveling crane positioned at the upper part of the furnace frame, and then fixing the periphery of the n-th furnace zone on the furnace frame; and feeding the m-th furnace zone into the furnace frame from the opening, lifting the m-th furnace zone through the traveling crane, and then butt-welding the m-th furnace zone and the (m+1)-th furnace zone, wherein m is equal to n-1, n-2,..., 2, 1, and n is a natural number.
Description
technical field [0001] The invention relates to a method for inverting a blast furnace shell in a hob. Background technique [0002] The blast furnace shell is sequentially composed of the first furnace zone, the second furnace zone and the nth furnace zone from bottom to top. When installing a blast furnace, the normal installation method is generally adopted, that is, the first furnace belt is installed first, then the second furnace belt is hoisted (lifted), and the second furnace belt and the first furnace belt are butt-welded, so that from bottom to top Install each furnace belt in turn. [0003] For the reconstruction of the old blast furnace, because the blast furnace is surrounded by the furnace frame, the driving height of the lifting blast furnace top is limited (the distance between the lower part of the driving car and the top of the furnace frame is small), and the furnace belt cannot be lifted above the furnace frame by driving. After moving horizontally, Put...
